Ukrainian drones set fire to Lukoil's Permnefteorgsintez refinery in the Russian city of Perm overnight, the second strike on the same plant in three weeks, according to the Kyiv Independent and Ukraine's General Staff, cited by UNN.
The plant lies in the Ural Mountains, among the deepest strikes of the war, per the General Staff (UNN). It processes over 13 million tonnes of crude a year at a refining depth of about 98 percent, among the highest of any Russian plant, and supplies the country's armed forces, per the same source. President Volodymyr Zelensky said the strikes are meant "to return the consequences of the war to where it came from," per PBS NewsHour.
The campaign has left Russia short of gasoline and diesel at home for more than three months, per an S&P Global analysis cited by OilPrice.com. Why it matters: Russia's refined-fuel exports feed global diesel and gasoline supply, so sustained outages at plants this size raise the risk of price pressure spreading beyond Russia's own pumps — though the scale of any global spillover has not yet been quantified.
Russia's defense ministry said it downed 325 drones overnight across a dozen regions stretching from Perm to Moscow and Crimea, a claim that could not be independently verified, per the Kyiv Independent.
What to watch: whether Kyiv keeps re-striking the same repaired facilities to keep them offline, and whether Moscow's mounting refining losses begin to show up in global diesel prices as autumn demand rises.
